ngx_tcc_module是一个nginx http模块，它把tcc编译器内嵌到nginx，用来编译C语言编写的网页后台脚本。
每个页面由两个文件组成：
*.csp，是主要用HTML编写的文件，里面会内嵌一些C代码。
*.c，纯C编写的代码文件，里面主要是做一些业务逻辑的处理。

代码示例：
index.csp
<%
/* This is a "c server page (CSP)" */
static int i;
%>
<html>
<head>
</head>
<body>
<% for (i = 0; i < 5; i++) { %>
<a href="<%=url%>" target="_blank"><%=title%></a>
<% } %>
</body>
</html>
